Does leaving a round in the chamber for extended periods of time cause spring fatigue or any other harm to the internal parts? Also, isn't this extremely unsafe? I have a s-40 and would like to be "ready", but unsure of potential damage to the gun. I had a cz-75 that had a hammer so you could leave a round in the chamber with no worry of accidental misfire. My gun has a manual safety, but what else does it have? The manual states it has a drop and firing pin safety, what are these? I know the drop safety is in case you drop the weapon, but how does it function?
